Formations to plow the surface layer of a land using modular agricultural implement of drag and respective components. It was developed to attend specific agricultural activities in areas of compatible dimensions and to carry out the overturning of the superficial layer of the soil, leveling, and/or incorporating correctives and fertilizers, as well as reducing compaction to increase porous spaces and increase the permeability and storage of air and water. It is assembled in modules under different forms of assembly, highlighting there are the triangular agricultural formation in three versions, triangle forward, triangle backward, and agricultural formation large triangle, and the agricultural formation in rhombus in two versions, the simple rhombus, and the large rhombus.
